Am diabetic since 1983 and I am suffering from constipation. The stool is hard like goat stool. My right foot is dead and the other is getting effected. I am using Zoryl M2 in the morning and m1 in the night, I started this medicine since 13 days ago. The sugar has gone down to 86. I want to ask you whether I should continue this medicine or I should change. Constipation is irritating and mouth gets dry it results bite on. Side of mouth Is it a saliva problem, I need your help.
